zostay how do i track down and diagnose the source of this error? Probable version skew in pre-compiled '~/.zef/store/http-useragent.git/0a0cb5bb42ec4a97057bbf53698bdc42a020399a/lib/HTTP/MediaType.pm6 (HTTP::MediaType)' (cause: no object at index 4850) 01:36
i tried nuking my rakudo install and installing fresh and i am getting it after installing everything again
01:38 ovechkin joined
zostay it starts showing up as soon immediately after i install a branch of URI i've been working on and from that point forward, any attempt to work with HTTP::MediaType causes death and peril, so that i can't even run zef install --force on HTTP::UserAgent to attempt to reinstall to see if that would help 01:39

Herby_ o/ 05:02
Evening, everyone
working my way through Think Perl 6 and am stumped on why I'm getting an incorrect answer to an exercise 05:04
05:05 dj_goku left
Herby_ I need to write a subroutine that gets the percentage of words that do not contain the letter 'e' 05:05
pastebin.com/dcVJdN0N 05:07
if someone could take a peek
there is a 5% difference in the final answer between those two ways of writing the subroutine 05:08
araraloren m: say "FOO" if "eaaf".index("e"); 05:09
camelia ( no output )
araraloren This return **0**!! 05:10
IS FALSE!
Herby_ m: say "foo" if index "eaaf", "e";
camelia ( no output )
araraloren So, this code is not correct 05:11
m: say 0.so
camelia False
araraloren m: say "FOO" if "eaaf".index("e").defined;
camelia FOO
araraloren Please refer this: docs.perl6.org/routine/index 05:12
Herby_ ahhhh
araraloren `index` will return undefined value when `$needle` not found
Herby_ m: say "foo" if "aaef".index("e");
camelia foo
Herby_ I see. That's a simple explanation. Thanks!
say "foo" if "eeaf" ~~ /e/; 05:15
evalable6 foo
Herby_ nice, evalable6 saw that I missed the leading m:
araraloren Yeah, use regex is a good solution.
`m` is optional 05:16
Herby_ on a 113k word list, would index be substantially faster than regex?
i should learn how to benchmark in p6
araraloren Yeah, index will faster than regex, maybe, it's difficult to say. 05:17
Herby_, for simple benchmark, you can refer this: docs.perl6.org/language/performance 05:18
Herby_ thanks araraloren. running it a few times and just eyeballing the average time, index was ~3x faster 05:21
on a 113k word list
zengargoyle Herby_: there is a Benchmark module. github.com/perlpilot/benchmark
Herby_ zengargoyle: thanks, I'll check that out 05:22
araraloren Yeah, I think Regex can also optimized
Also `Regex` do more thing than `index` 05:23
zengargoyle index will always be faster. no need to create the match object even if the regex is crazy smart enough to realize /e/ could be a simple index. 05:25
araraloren yeah 05:26
05:26 Cabanossi left
zengargoyle at least in p5 it *totally* makes a big difference with large data even without all the objecty stuff. :) 05:27
05:27 Zoffix joined
Zoffix m: say "foo" if "aaef".contains: 'e'; 05:27
camelia foo
05:28 Cabanossi joined
zengargoyle where *large* is just small but it makes the difference between a fast CLI tool and one that makes you grumble while waiting. 05:28
Zoffix m: say 'foo' with "eaaf".index: "e";
camelia foo
Herby_ Zoffix o/
m: say 'foo' if "eeaf".index: "e"; 05:29
camelia ( no output )
Zoffix ksn00b: if you mean for Inline::Perl5, then `use lib:from<Perl5> <some/dir>;`
\o
araraloren yeah, `with` is short for `if .defined` 05:30
Herby_ ahh ok
Zoffix m: <just a bunch of words with letters and other interesting stuff>.categorize(*.contains: 'e').say
camelia {False => [just a bunch of words with and stuff], True => [letters other interesting]}
zengargoyle would a 'so' work? 05:31
Zoffix `with` also aliases the value to $_
Herby_ Zoffix: that's pretty damn neat
haven't seen categorize yet
Zoffix m: printf "%.2f%% of words have letter 'e'", 100*.{True}.elems/.values».elems.sum with <just a bunch of words with letters and other interesting stuff>.categorize: *.contains: 'e' 05:33

08:58 Cabanossi joined
zengargoyle has nasty memories of teachers marking things wrong because that wasn't the stuff you were supposed to know at the time. 08:58
lizmat tries to recall...
could be that sets/bags/mixes didn't make it to the book 08:59
El_Che morning
lizmat vaguely remembers having a discussion about that with lolo78
El_Che hopefully less hot in your part of the world :)
lizmat checks outside
zengargoyle they are there, i'm just at them now, but the word stuff was many chapters ago. 09:00
so not introduced when solving the original question about index(). 09:01
lizmat El_Che: 28.9 in the shade atm
El_Che For the record. I am not trolling about ugexe's or nine's work on the blog post. Just exited about the CPAN integration and wondering if this could result in an even better experience than Perl 5.
lizmat El_Che: that's how I've interpreted the blog post :-)
El_Che just in case. We can all be a little protective of our babies :) 09:02
zengargoyle i'm groaning about having to go back and make MANIFEST files for my modules which i guess is a byproduct of CPAN 09:04
El_Che the info is already there in the JSON file, I guess
zengargoyle on that modules.perl6.org/todo thingy all of mine note missing MANIFEST so i guess it's not smart enough to figure out from the info 09:06
and there are always resources and things that i don't think go in meta anywhere. 09:07
lizmat doesn't mi6 have a MANIFEST generation feature ?
zengargoyle maybe now. not then. i used mi6 for at least one of those modules. but it's been a long while.
and i saw somewhere a 6zilla or something but haven't investigated yet. 09:09
09:12 sammers left, vytautas left 09:13 vytautas joined 09:14 wamba joined

09:16 xtreak left
zengargoyle and change all my travis files to use zef. :P 09:17
and maybe sign up or whatever to get things tested on a windows ci system
which i know absolutely noting about. :/
lizmat zengargoyle: please let us know how that goes 09:18
and use the new zef / mi6? CPAN Testers functionality to hand in test reports
zengargoyle lol, i asked a few days ago if anybody had a recent blog post or HOWTO about current best practices. 09:19

zengargoyle i think it would be neat to `git clone git:gitnub.com/perl6/ecosystem-module-template.git my-module` and read a TODO and change some META and always have a bells and whistles Acme::HelloWorld module 09:28
lizmat isn't that what "mi6 new Foo::Bar" does ? 09:30
or could do ?
09:37 dogbert17_ left 09:40 zakharyas joined
zengargoyle yeah, maybe. i haven't actually tried recently, just ponderning. :) and wondering if mi6 has any official standing or is just the current favorite. 09:40
lizmat zengargoyle: I don't think anything has an "offical" standing, as rakudo itself is only *an* implementation of Perl 6 09:42
zengargoyle just thinking that some sort of CUR could do a fake install and then generate actual MANIFEST like installing to a DESTDIR with make in order to make a tarball does.
lizmat you *can* write your own CUR
PR's welcome :-) 09:43
zengargoyle yeah, just thinking about how much i always hated MANIFEST and MANIFEST.SKIP and all the times some p5 module building system yelled at me or did something wrong. 09:44
09:45 yqt joined
zengargoyle and the stuff installed is defacto the MANIFEST. :P 09:45
except for all the tests and readme and oh, nevermind... bad idea... 09:46
09:46 wamba left
zengargoyle part of me actualy wants the CUR to keep everything that's in to repo. i always end up downloading the src to look at tests or examples anyway. 09:48

nine .tell Zoffix That's weird. When I fatalize INDIRECT_NAME_LOOKUP the code dies every time on the first attempt. This however works reliably: sub app (|args) { return (require ::("GTK::Simple::App")).new; }; 10:09

zengargoyle hrmmm... zef install App::Mi6 does nothing. 10:10
/install/fetch/
10:11 jnthn joined
nine zengargoyle: does it do nothing or does it just not print anything? 10:12
zengargoyle: if it really does nothing, then maybe it already has got it in its cache?
zengargoyle it says: '===> Searching for: App::Mi6' then exits with no errors or further information and doesn't give me a directory with app-mi6 or something. 10:13
does fetch not do what i thought fetch should do? 10:14
seems so, look drops me into ~/.zef/store/*long_hash*/ 10:15
my expectations were in error. :) 10:16
10:18 mr-foobar joined
nine zengargoyle: I think at some point we actually wanted to install tests and everything. It just fell on the wayside in the sprint to release 6.c. This can change however :) 10:19
zengargoyle cool, i'll put it in my mind like making a native executable by squising moar + repository into a single file. :) 10:20
App::Mi6 only ack's MANIFEST.SKIP so i don't think it generates one but looks to just ignore things in the .SKIP when doing the CPAN upload. 10:22
note "If you want to ignore these files, then list them in .gitignore or MANIFEST.SKIP";
more of a clean repo before uploading than auto MANIFEST file generation. 10:23

timotimo araraloren: you were giving the same $i to all the started pieces of code in the loop example. so they got started on the thread pool, and printed the value, but in the mean time the loop already incremented the value 10:42
10:42 wamba left
timotimo araraloren: but in the for loop case you get the value bound to a parameter on the inner block, so it was a fresh scalar every time 10:43
10:43 Cabanossi joined
zengargoyle is there a reason NativeCall doesn't try to search for versioned .so files and pick the highest one (if no version is requested)? 10:44
timotimo: the two loops don't give the same values in the first place. 10:45
araraloren timotimo, so what should I do to get the same result.

no exception now
jnthn No, that's just how Promise.allof works 10:57

camelia Can only use allof to combine defined Promise objects

moritz araraloren: you can also await a list of promises 10:59
jnthn You can...what moritz said :)
araraloren Oh, this just a test, I want run some code concurrent, so the main thread should wait them done
lizmat and even handle them one by one:
for awaiterator(@promises) -> $p { check the next promised that reached a conclusion } 11:00
araraloren I just want know is rakudo will not report when an exception raise ?
11:00 eliv left
jnthn araraloren: Then await the promises; you don't need Promise.allof 11:00
araraloren when use Promise.allof
jnthn No, it won't. If Promise.allof did that, then it'd do the same as await @list-of-promises and there'd be no point to having it :) 11:01

nine thundergnat: not a good one :/ I think, I'm just gonna exclude all lower cased modules from importing. By convention those should all be pragmas. 20:46
thundergnat geekosaur: The thing that really confuses me; if you uncomment the "say @d" line, it get the same thing in every instance, it just gives a different result for the .comb 20:47

nine: BTW, thanks for making it in the first place, the awesome greatly outweighs the WAT. :-) 20:50
lizmat: The weird thing is that the d sub gets an array from .comb like every other instance, it just treats the array subindexing differently. 20:53
lizmat because it gets Str as indexes
thundergnat as does <1 1 0> but _that_ works as expected... 20:54

m: my @a = ^10; dd @a["5"] 20:56
camelia Int @a = 5
lizmat there shouldn't be a difference
thundergnat Want me to rakudobug it?

thundergnat lizmat The other odd thing; if I do the subscripting as @d[$r][$c] ( rather than @d[$r;$c] ) it works as expected in all cases. 20:58
lizmat thundergnat: yes please
yeah, so the [;] candidate handles Str differently 20:59
definitely rakudobug this :-)
thundergnat ok :) Thanks for the assistance (and all that you do. lizmat++ ) 21:00
lizmat thundergnat: yw :-)
Herby_ random question 21:13
I noticed a small typo in the Think Perl 6 book on a code section. Anyone know the best way to relay that to the authors Laurent Rosenfeld or Allen Downey? 21:14
didn't know if Lauren hangs out on this channel
Laurent 21:15
lizmat lolo78 if he's around
Herby_ thanks
just found a way to submit the type on oreilly's site 21:16
MasterDuke there's also a github repo

tbrowder question: one line in Pod::To::Text is "$pod.map({pod2text($_)}).join("\n\n")" and I need to unwrap that statement if possible. can anyone show how to do that? thanks. 23:37

kurahaupo tbrowder: $pod is a list, {pod2text($_)} is a small anonymous function, and .map is a method that applies a function to each element of a list and returns a new list of the results 23:43
23:44 TEttinger joined
kurahaupo tbrowder: then the .join method is applied to that resulting list, to return a single string. does that help? 23:46
tbrowder thanks, but is there a way to break that into a named function with separate, simpler statement? the line is returning an error that is hard to debug in its present form 23:47
Herby_ Zoffix: That's awesome. Congrats on completing the grant work
